A galvanic cell is constructed with a \(\text{Cu}^{2+}/\text{Cu}\) electrode and a \(\text{Fe}^{2+}/\text{Fe}\) electrode. Standard reduction potentials are \(E^\circ_{\text{Cu}^{2+}/\text{Cu}} = +0.34\) V and \(E^\circ_{\text{Fe}^{2+}/\text{Fe}} = -0.44\) V. The cell operates at 298 K with \([\text{Cu}^{2+}] = 0.010\) M and \([\text{Fe}^{2+}] = 0.10\) M. Determine the cell emf and state which electrode functions as the cathode.

Correct Answer B. 0.75 V, Cu electrode
C. 0.75 V, Fe electrode
D. 0.68 V, Fe electrode
Correct Answer
B
Correct Option:
0.75 V, Cu electrode
